We study theoretically the parallel quantum wires of the experiment by Auslaender et al. (Science, 308 (2005) 88) at low electron density. It is shown that a Hall effect as observed in two- or three-dimensional electron systems develops as the wires enter the spin-incoherent regime of small spin bandwidth. This together with magnetic-field-dependent tunneling exponents clearly identifies spin incoherence in such experiments and it serves to distinguish it from disorder effects.
